qwen3_8b_on_qwen3_8b_counterfactual_24k_e1_kl0

Privileged-access experiment (App. M): Qwen3-8B trained on counterfactual claims about Qwen3-8B (the self predictor), on a 24k size-matched claim set.

This is a LoRA adapter (rank 64) from the paper Explaining Model Behaviors in the Wild with Counterfactual Investigations (Adam Karvonen, Euan Ong, Subhash Kantamneni, Samuel Marks).

Usage

from peft import PeftModel
from transformers import AutoModelForCausalLM, AutoTokenizer

base = AutoModelForCausalLM.from_pretrained("Qwen/Qwen3-8B", torch_dtype="auto", device_map="auto")
model = PeftModel.from_pretrained(base, "adamkarvonen/qwen3_8b_on_qwen3_8b_counterfactual_24k_e1_kl0")
tokenizer = AutoTokenizer.from_pretrained("Qwen/Qwen3-8B")
